very emotional today

Towards the end of 2015 (October-November) is when my boyfriend and I started trying to conceive but not really tracking and having sex when I was ovulating. That went on until maybe July of 2016. Then I started tracking my ovulation. It's been about 8 months, Still nothing. 
So technically it's been over a year and half since having unprotected sex and not getting pregnant. 
I've stopped tracking my ovulation and pretty much stopped trying to conceive. But I still get depressed every time AF shows up since we aren't using protection. 
AF showed up today, and I'm very emotional since it seems like everyone around me is pregnant or just had a baby. 
I don't even know what else to do 😓
